Maybe I have missed it, but I can't seem to find a tutorial on how to use this software. It looks easier than using EasyuseTools. Can someone help me out on where to find it? Thanks

Hi you can find details on what the buttons do HERE

Ok, let me see if I have this correct..........I updated my TomTom One in Dec 2008 from Underground..........I see that the tools have changed. I backed up then deleted the map from the TT. I downloaded the 845.2666 Usa_and _Canada map. I then uploaded that map the TT. I started the keygen, but when I click on "Make Map Keys" it tells me that the truck maps are corrupt and I guess never does what it is supposed to. Am I missing some steps somewhere or is the map download corrupt? Though, I didn't download truck maps to begin with, do I have the right keygen to patch the map file?

connect your GPS to your PC

then run KEYGEN 4.1D [color="Red"](no virus in this keygen, ignore AV warnings)[/color]

then select MAKE MAP KEYS

then click on CREATE DCT [color="Red"](ignore truck map errors)[/color]

your done!

Thanks, I finally just went back and used Easyusetools again. Worked fine........but thanks for everyone's help.

KEYGEN 4.1D is the way to go these days though :P
